"Home Sweet Home. That has never had quite so much meaning before," the "Good Morning America" anchor, 51, wrote on her blog, which also featured photos of Roberts exiting the hospital with a face mask and protective gloves, and relaxing on her couch and gazing out the window.

To combat her MDS, doctors transplanted bone marrow donated by the veteran journalist's sister, Sally-Ann. "My doctors tell me her cells are making themselves right at home and with the grace of God, I pray that they will continue to do so," Roberts writes.

But, she points out, "This doesn’t mean that my journey is over. Far from it." The star's "GMA" hiatus will continue "until I'm given the all clear, but sleeping in my own bed feels like a big victory. My doctors will be monitoring me closely and I will still be at the hospital regularly to make sure we’re on the right track."

Thanking her "amazing medical team," Roberts also acknowledges the support of her fans. "I know it is your prayers and warm thoughts that have gotten me this far. I truly feel them each and every day. I humbly ask that you please continue to send them until you see me back at the GMA anchor desk and I promise to send them right back at ya."
